H. LUNDQUIST LAGE THREADING MACHIE Filed April 23. 1921 6 Sheets-Sheet 55S l? #Jig Jan 8 H. LuNDQulsT LACE THREADING MACHINE :filed p1-11,23.1921 6 Sheets-Sheet 6 permitting of considerable reduction of speed.This gear 8 Yon the shaft 4 receives its drive from a similarlyconstructed pinion 9 on the shaft of the motor 2; the reduced speed ofthe shaft 4 is transmitted to the shaft 5 through a gear 10, mounted onthe other end of the shaft 4 in mesh with a gear 11 of equal diameter,fixedly secured to the corresponding end of the shaft 5.

IThe shaft 5 carries at the other end a bevel pinion 12 secured to areduced portion of the shaft, and in driving relation with alongitudinally disposed shaft 13, Fig. 3, which is supported at itsfront end on a. bearing bracket 15 and which may be snp ported on theother end in some suitable way not shown in the drawing.

The rear end of the shaft 13 has a bevel gear 14 in engagement with thebevel gear 12 of shaft 5, and the front end projecting beyond thebearing bracket 15 carries a crank disc 16 on which a crank pin 17 iseccentrically secured, Fig. 2.

A lever 18, having a pivotal support "19 on top of a bracket 20, has abiturcated rear end 21, which embraces the crank pin 1T, the depth ofthe bifurcated portion being sufciently large to permitof the rotarymovement of the pin 17 and to cause at the same time the oscillation ofthe lever 18 about its pivot 19. A transverse head is secured at the endof the bifurcated portion 21, as indicated in Fig. 2, to preventaccidental displacement of the lever and the crank pin 17.

The opposite end of the lever 18 is also bifurcated, as shown at 22,Figs. 2 and t. and embraces a transverse pin 23, which is securedbetween rearward lugs 24 of a cross head 25 guided in a verticalstandard 26. In order to permit of an exact adjustment of this standard26, it is placed between lugs 27'. Fig. 6, which rise from the baseplate 1: holdin plates 28 are secured on top of the lugs 2 by means ofscrews 29, whereby these plates may be clamped against the foot of thestandard to retain the same in adjusted position. Pressure screws 30.which extend through the foot of the stand ard 26. may serve forincreasing the clamping effect produced by thc plates 28 on thc lugs 27.This standard, as will be seen from Figs. 1, 2, 6 and 7, is providedwith lateral vertical guideways 31, into which the lateral extensions 32of the cross head 25 project. Displacement of the cross head forwardlyor rearwardly is prevented by the ribs 33 of the standard and by theplates 34, which are secured to the front face of the standard.

The cross head 25 is also provided between the top and bottom surfacesof the saine with a projection 35, Fig. 6, in which a rock shaft 36 isrotatably supported. The cross head. furthermore, is provided with avertical bore 37, which communicates with that cavity 38 into which therock shaft 36 projects. The inner end of the rock shaft 36 carries abevel gear 39 in engagement with. a bevel gear 40 at the lower end of avertical rock shaft 41 supported in a sleeve 42. the reduced portion 43of which is fitted into the bore 37 of the cross head. The rock shaft 41is ixed against rotation with respect to the sleeve 42, as shown in Fig.6, and projects beyond the sleeve. To the projecting end a crank 44 isfixed, and the free end of this crank is integral with a verticalextension 45 having a central borc and an outer thread. A holding pin 46is slidably secured within the bore of the crank 44, and the reducedportion 47 of this pin is surrounded. by a spring 43 in the interior o'the extension 45, this spring rest-ing at one end on a shoulder of thepin and being forced thereby against the closing surface. of anadjustable cap nut 49 which rides on the threaded outer surface of theextension 45.Y That end ot' the pin 46 which projects through the rapnut 49 is threaded and carries a nut 50 whereby the downward movementimparted to ghe pin 46 by the spring 48 may be lim.- iter..

A bracket 51 is secured to the rear surface of the cross head 25, Fig.6. and carries at its top a lateral arcuate extension 52, Fig. 3, havinga plurality of sockets 53 into which the end of the pin 46 may enter tolock yieldingly the crank 44 and hence also the shaft 41 againstrotation with respect to the cross head. lf it 'is desired. however, toadjust the crank 44 in order to rock thereby the shaft 41, it is onlynecessary to lift the pin 46 against the tension of the spring 48,whereupon the crank may be rotated to the desired extent. lt may thenagain be yieldingly locked in its new position by permitting the pin 46to ent-er a different one of the sockets 53.

The part rotation which is imparted manually to the crank 44 istransmitted through the bevel gears 40 and 39 to the shaft 36. Thisshaft. as may be seen from Figs. 2 and 6. carries at its free end a4rigid extension 54, which terminates in a` knob or shoe 55. An annularprojection 56 of the sleeve 42 supports rigidly a rod or bar 57, whichis pinned to the projecting portion. The free end of this bar 57 also isin rigid connection with a tubular elbow bracket 58, as illustrated inFigs. 6 and 8. in which another gripping shoe 59 is yieldingly held andforced normally into engagement with the companion shoe through a spring60 in the vertical tubular arm of the bracket 58, this spring resting atone end at the bottom of the bore and at the other end against ashoulder 61 on an enlarged portion 62 of a stem 63 with which the shoe59 is united. The extension of the stem 63 is threaded and projectsbellt) lill) also to both of the grip yqnd the v .rtical arm ot etiibular bracket. To vary the resiliency o the sprintf 60 a set of locknuts 64 rides on the threat ed extension of .the stem 63,. The spring6() has a tendency to torce the shoe ,oiitwardlyg the outward movei'ientbeing limited by the engagement of t e lower one of the nuts (34 withthe top epd of the vertical tubular arm on the bracket. `Rotaryn'lovement of the stem, 62 about axis is prevented by u. pin Q5projectin from the same into a vcrtial slot 66 pf t e bracket 58.

than the crank'44 is turned about the airis of tie shaft 41 the `llppingshoe 59 also will e turned about t le same axis, and at the sume timethe gripping shoe 55 will be turned about the of the shaft 3 6, that is,about an agis extending at right angles to that.; about which the shoe59 is rotated,

gy the rotation of the shaft 13 an oscillating movement is imparted totheI lever 18 and a reciprocating movement thereby transmitted to thecross head 25, and hence ing shoes 55 and 59, which are yieldingly hedin Contact tlirough the spring 60.

The standard 26 also carries a bracket 67, 1, projecting laterally fromthe same, @misil` porting at its puter end a clamping shoe 6 pn whichthe threading needle 69 is removal'ily supported. This bracket (ST, aswill be seen from F 3, supports the clamping head Q8 through arelatively long Mul T0, which projects at right angles to the plane ofthe bracket.

e main body of the needle 69 is of known construction. It consists of a.relatively straight shank 71, the end of which is embraced by aclampingr ring 72, held in adjusted position by a set-screw 73 The shankTl emerges into a loop 74 of approximately helical shape, F ig. 3. Theend ot this needle is in detachable connection with a needle point 75.preferably made of a lat piece of met-al, (Fig. l), and this point has arelatively long eye r(6. This threadingr needle has, longitudinalgrooves 78 in which one or more tapes or threads may be inserted, theportions of this tape or thread being: guided by the clamping ring 72and partly by a clip 7T located near the connecting end of the needlepoint and bridging the longitudinal grooves. The front ends of theseAgrooves have laterally deflected portions T9 to assist in retainingrthe ends ot the tape or thread in position, and to prevent an accidentalwithdrawal of the same.

While in lace threatflinf,r machines of known construction the advanceor feeding movement of the lace ordinarily is eiected by rollerscontacting the lace from opposite sides and frictionally pulling thesame through between the gripping shoes, the present invention providesmeans for posi- @Yeh feeding the les@ .is a Stepby Step mvement, at theSame time permitting 0f a variation of this feeding step in accordancewith the character ot' the lace. The mechanism, Figs. 1, 3. 4, and 5,for eiiectinzgr this step by step positive feeding movement ot the lace,includes two substantially similar quadrilateral frames 80 and 81,respectively, each rockably supported through hubs 82 on the shafts 4and respectively. Each of these trames or yokes consists of the twoparallel longitudinal arms 83 and ot the transverse arms 84.-; the upperframe 8,0 furthermore has a forward extension 85` to Which a chain 86 isconnected. A pin 8T projects from the front of the upper yoke 80 againstthe lower yoke, to limit the distance to which the front ends mayapproach each other, Fig. 4. The rear ends of the two frames, however,on the other side ot the shafts 4 and 5 are yieldingly interconnected bysprings 88, which are attached at their lower and upper ends to pins 89,projectingr trom the arms 83 outwardly. Fig. 3.

One huh S2 on each frame has a gear sector 95, the sectors being inmesh, whereby, upon a pull upon the chain 86 a swingingr movementdownwardly is transmitted to The upper yoke 80, and at the same time theother yoke is, owing toV these sectors, swung upwardly V(against thetension of the springs 88), until contact of the pin 8T with the loweryoke stops this movement. Upon release of the chain 8B both frames arepulled apart at their front ends by the Sprin's 88- Each of the frames80 and Sl carries at one of the longitudinal arms a rock shaft 90extending transversely between the arms 83 and beyond the same. Thisrock shatt 90 in each frame is rigidly connected through the hub 96`with anarm 91, which carries a roller 92 engaging a cam groove 9.3 inthe discs 94` which are keyed to kthe shafts 4 and 5, respectively. Bothof these arms 91. therefore, are underV the control ot' the cams 94 andthe shafts 4 and 5, whereby the shafts 90 will be oscillated.

Fig. 5 clearly 'shouts that the arrangement of the discs 93 on the twoshafts is very eompendious and permits the entire structure to becrowded into a relatively small space, the arms 91 on both of the shaftsbeing approximately in the same vertical plane and having` the rollers92 oppositely directed to enter the cam grooves 93 of the pertainingycams 94. It the yokes 80, 8l are converted into a rigid structpre (Fig.4), through a pull on the chain, the rotation of the. cams 94 will causeoscillation of the rock shaft. But if the chain is released and thetrames are yieldingly supported, owing to the action of springs 88. therotation of the cams will merely cause the frames to oseillate about theshafts 4 and 5, respectively.

The rock shafts 90 carry each at their free ends a sleeve 97 which ispinned thereto and which extends at right angles to the axis of theshafts 90. The sleeves 97 will, therefore, also he rocked about the axisof the shaft. The sleeves have lateral tubular extensions 98 throughwhich they are fastened to these shafts 90, the latter being advisablysupported in bearing lugs 00, which project from the longitudinal frameparts 83, Fig. 3.

The sleeves 97 each serve for slidahly supporting a rod 100, and theserods have at their forward ends angular arms 1.01, terminating inoppositely directed pins 102 and 103, respectively. Those ends oftheangular arms 101 which are secured to the rods 100 are threaded, wherebya longitudinal ad justment of these arms is made feasible and each armmay be held in adjusted position by a lock nut. The rods 100 whichsupport the pins 102 and 103 respectively being oseillated by theenforced oscillation of the sleeves 97 it is obvious that the pins 102and 103 are also oscillated up and down, or rather in the arc of acircle having its center in the axis of the pertaining rock shaft 90.

The pins 102 and 103 terminate in reduced extensions 104, which enterthe mesh of the lace and then again recede from the same. Means are alsoprovided for longi tudinally reciprocating these pins 102, 103 wherebythe lace is fed, owing to the impact or push of the extensions 104against strands of the lace. This is accomplished through means whichlongitudinally displace the rods 10,0 for the feeding pins.

The rear ends of these carriers or rods 100 are equipped with heads 105,Which are hifurcated, as indicated at 106 in Fig. 3. Crank rods 107.terminating in flat eye portions 10S, are pivotally connected with theseheads, and the opposite ends of the crank rods 107 are detachablyconnected with crank pins 109.

The crank pins, as may be seen from Fig. 1, are mounted on slides 110,Which are movable in guideways 111 on the discs 112, keyed to the shafts4 and 5, respectively. and which are also associated with the gearWheels 10, 11, Fig. 5.

rlhe guideways of these discs are partly covered by segmental plates11S, which can he clamped against the faces of the discs 112 by thescrews 114. When properly rlaniped in position they will retain theslides 110 immovably in the adjusted position. whereby the throw orstroke of the pins 102 and 103 may he selected arbitrarily not only asto length, but also as to timely relation with the companion pin.

The operation of the device Will become apparentl from the abovedescription. The various steps, which are repeated with great speedwhenever the engine is in operation, are illustrated in Figs. l1 to 14,inclusive. lf it is desired, for instance, to insert a tape T into thelace L, this tape is placed on the needle 60 so as to he presented tothe lace in the shape of a spiral loop, the free end of the tape beingsecured on the needle by the clip 77, which bridges the grooves near thefront end of the needle. The tivo gripping shoes 55 and 59 are thenswung to inoperative position by rotating the crank 4l after theyielding locking pin 46 has been released from the pertaining socket 53,and in this released position the shoes 55 and are also held locked bypermitting this pin 46 to enter another socket of the arcuate extensionon the bracket 51. ln order to prevent rotation of these gripping shoesand 59 in a predetermined direction the shaft 36 of one of these shoescarries a pin '115, which, aS will he seen from Fig. 1, is held. againstrotation in a certain direction by a pin 116 projecting from the face ofthe cross head 25. The chain 86 is released permitting the springs 8.8to pull the yokes apart at their front ends so that the feeding pinsalso occupir the position indicated in Fig. 10.

The lace i5 then placed with its end on the eye piece 75 of the needle,and the shoes 55 and 59 are returned into the position in which they areshown in Figs. 11 to 14. This is the operative position of the two shoesin Which they grip the lace and alternalely move the saine, owing tovertical reciprocating movement of the cross head 25 above and below theeye piece 75 of the needle.

lVhen then the operator depresses the treadle (which is not shown), thefeeding pins 102 and 103 are also moved towards each other in a verticalplane, so as to occupy approximately the position illustrated in Fi 11,and it will he understood from a reterence to this ligure and referenceto Fig. 1 that the extensions 104 on these pins are not in directopposition to each other, the crank pin 109 for the lower pin 103 heing, for instance, at the left side of a vertical line which extendsthrough the axes of the pertaining crank dises, While the upper crankpin 100 is at the right side of the saine line. The pin rods 100,therefore, do not project to the same extent from their sleeves 97 andit will also be obvious that in the continued rotation of the crankdiscs 112 a similar relation of the feeding pins will he maintained.These feeding ins, therefore, will cach move in a substantiallyelliptical path, produced by the combination of the movement due to theoscillation of the sleeves 97 and the movement of the crank pins 109.While traveling each through this approximate elliptical path, the pins`:vill move oppositely to each other; one pin, as for ifo ine'tebce,102, feeding ic directien meerde tbe needle e9 wbeb tbe 'other1 pie 10ele meving in direction toivards the lace, as indicated et Fig. 12.
